We would use is_readonly in order to remove some extra checks from btrfs (setxattr, removexattr, possibly setsize). > If there were other users of ->is_readonly, then it would make sense, > but it seemed better to move into a separate code refactoring series. Yeah it would be better addressed separately as it's not the point of lazytime patchset and only turned out to be a good idea during the iterations. -- To unsubscribe from this list: send the line "unsubscribe linux-ext4" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
